An interesting question might be, if we don't have free will, why does it often or generally feel like we do?
It's hard to think of something that would make us not have the ability to act of our own accord. I mean, it's like the question 'If we humans don't have the power to type on our keyboards, why does it feel like we do?'. Well, the evidence that I have that power is beyond a reasonable doubt, so if we don't have that power, something
very weird would be happening, though I have no clue as to what it is.
Similarly, if we do not have the ability to write these posts of our own accord - for which we have conclusive evidence -, something really weird must be happening.
Note, however, that while I can see that I have the ability to do stuff of my own accord, it
does not feel like my choices are not broght about by previous causes. I'm not even sure what that would feel like.

No one knows, but one possible/plausible answer is that however the belief initially arose, humans today are the resultant survivors of a process of natural selection that has selected for that belief, because having the belief may be useful, for reproduction and survival, regardless of the truth or falsity of the belief.
But something very weird would be happening here, because of what it would take for that belief to be false - the belief that we can act of our own accord, which is rather obvious -, as in the case of the power to type above.

The Compatibilist Daniel Dennett suggests that if we lost our belief in free will, we would not work as hard to achieve things, and also that humans would not act in ways that sustain the societies on which our survival depends.
It's very hard to imagine how a human could lose that belief, so who knows. What is easy to imagine is how a human could gain the belief that we cannot act of our own accord, but that would leave him with contradictory beliefs, since he would not lose the belief that we act of our own accord, most of the time.
Now, I think if we gained that belief, it would only interfere with our actions sometimes, and the rest of the times, we would go around as usual.

Or Dennett might be wrong, and worrying unnecessarily.
Worrying unnecessarily if he thinks that that is a significant risk, because it seems the odds that humans would lose that belief (rather than gain one that contradicts it) is almost zero.
How would it happen, without genetic engineering?
On the other hand, if he's worried that the belief that we cannot act of our own accord will be harmful like a widespread religion, that might be so, but still unlikely, as it would likely lose out to other religions.

It was said of both atheism and our evolution from apes that the consequences for humanity would be bad if they became widely accepted beliefs, and that has not happened. In fact, if anything, the signs are that stronger beliefs in those have resulted in generally more benign outcomes, as indeed weaker beliefs in free will appear to do. My own view is that humans can probably cope with and may even benefit overall from at least a weakening in beliefs in free will. Sometimes we just seem to fear change, for no good reason.
A big difference is that those beliefs are true, whereas the belief that we cannot act of our own accord is not.
Another big difference is that the belief that we can act of our own accord is tied to our moral concept of blameworthiness - as you noted. The ability to make blame judgments is a human capacity, and its exercise is part of what a properly functioning human mind does. Without it, you end up with a damaged mind.
On the other hand, the belief that we evolved from other apes or that there is no omnimax agent does not require suppressing any proper function of a human mind.
